[7300 GS] Intermittent GUI hangs in 12.04

Here is a link to the dmesg at the time of the hang (it's the same as that pointed to in the forum entry):

http://pastebin.com/JNVDHcyg

Status changed to 'Confirmed' because the bug affects multiple users.

Could be a dup of bug 887390

Another data point, this seems to be related to the multiload indicator that shows multiple bar-graphs in the Gnome panel. I switched to this type of system indicator when upgrading to 12.04 (I previously used a different one that showed only a single bar graph, but I could not find that one again after I updated)

Here is a link to the multiload-indicator that seems to be causing the problems:

http://www.omgubuntu.co.uk/2012/02/easily-monitor-system-resources-in-ubuntu-with-indicator-multiload/

Note that I use this in the gnome-panel (below) rather than that indicator bar that it at the top.

Since I have disabled this multiload-indicator, the problem has not happened once.

Happened again, and I have not been using the multiload indicator:

And again, this time very shortly after a reboot and the current version of the multi-load indicator was reinstalled (it had not been installed the past couple of times).

I think "hang" is too strong a word for this problem. The mouse pointer is still active, which may matter quite a lot in debugging this. A hang where the entire display is frozen, pointer included, is more dire.

Yes this is exactly my symptom. I can make this happen pretty mush at will and I can ssh to the machine from another and do whatever is necessary. Is there anything I can do to help capture more information?

Is there a later driver that I can get and install myself?

Switching to the NVidia driver makes this problem go away as expected.

I installed ubuntu 12.04 on a "AMD Sempron(tm) Processor 3000+" machine.
Kernel 3.2.0-24-generic-pae.
No X was installed. I still have (harmless?) occasional "general protection fault". The machine also got locked up completely once or two.

See the attached dmesg for the details.

forgot to attach

Note the time closeness between "Setting dpms mode 0 on vga encoder (output 0)" discussed here and the "general protection fault" messages:

Francis, others using X, if this is happening to you, please attach the output of

$ /usr/share/bug/xserver-xorg-core/script 3>&1

.

I can not reproduce presently since I'm logging in with session type "Ubuntu 2D" and it's not (AFAIK) using the GPU any more.

Also effecting us, multiple times a day. Please find output from
 $ /usr/share/bug/xserver-xorg-core/script 3>&1

Running kubuntu, it was an upgrade from 10.04LTS

Hangs like this have been happeneing randomly for me, since the 12.04 release. Again, the hang is mostly screen freezes, except for mouse. Sometimes, it locks the keyboard out, as well. And I have to use Sys-rq to reboot.

Finally decided to report it. :)

I have attached the output from that script.

Might go and try the nvidia drivers, but support was awful for my card in previous releases.

Francis Upton, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-nouveau REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.

We appreciate that this bug may be old and you might not be interested in discussing it any more. But if you are then please upgrade to the latest Ubuntu version and re-test. If you then find the bug is still present in the newer Ubuntu version, please add a comment here telling us which new version it is in and change the bug status to Confirmed.
